2G/3G Transmission Sharing
Why– In fact, almost all 3G sites co-located with 2G sites– Reduce CAPEX (in total) to upgrade existing capacity is
cheaper than build a new one– Reduce network complexity– Save tower and transmission floor space– Not to deteriorate network performance the more
microwave link deployed the more frequency interference potential
– Limited resources on frequency– Reduce the complexity to operate the network the more
nodes installed the more complex to operate
Consolidated network plan– 2G and 3G in 1 plan table
